CARBURETER.

SPECIFICATION forming part of Letters Patent No. 679,019, dated July 23, 1901. Application filed September 1, 1900. Serial No. 28,843. (No model.)

To aZZ whom it may concern:

Be it known that I, GUSTAV FISCHER, m echanician,residing at Riesa,nearDresden,King dom of Saxony, Germany, have invented certain new and useful Improvements in Carbureted-Air Producers; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention has reference to an improved 1o carbureted-air producer in which the production of carbureted air is automatically regulated by the demand of air-gas. The apparatus is constructed in such a manner that it is enabled to carburet air with all i5 kinds of liquid hydrocarbons and to burn completely also heavy hydrocarbon, so that the produced air-gas is suitable for illumination, cooking, and the supplying of power.

In the accompanying drawings such acar- 2o bureted-air producer is represented in Figure 1 in combination with a hot-air motor. Fig. 2 is a vertical section through the apparatus; Fig. 3, a horizontal section of the carbureter on the lines I, II, III, and 1V. Fig.

4 is a vertical sectional View, partly in elevation, of the pressure-reducing device. Fig. 5 is a horizontal sectional view through the upper portion of the vessel 18 of the pressurereducing device, showing the weight which 0 operates the valve 20 in dotted lines.

The apparatus consists, essentially, of the carbureter A, a blower B, a motor 0 to actuate the latter, an air-accumulator D, and one or more air-pressure-reducing devices and 5 the necessary attachments.

There is nothing special in the construction of the motor O and the blower. In the drawings the hot-air motor and the blowingengine are of well-known construction.

The carbureter A, Fig. 2, is of the following construction: A closed vessel 3 is provided with a filling device 1, an indicatingtube 2, and an air-feeding tube 4, terminating toward the bottom of the vessel 3 in a 5 chamber 5. The bottom 6 of the chamber 5 is formed by the finely-perforated thin metal plate or a fine-wire sieve, so that the air passes into the liquid hydrocarbon in the form of many fine jets. On the air-feeding tube 4 is provided another chamber 7, in which are arranged a number of horizontal vanes, forming a turbine wheel 8. The space over these vanes of the tube l is completely closed, and from this space lead one, two, or more radially-terminating tubes 9 to the chamber 7, Fig. 3. On the lower part of the turbinewheel axle 10 there are arranged one or more brushes 11, turning with the axle 10 and sliding over the perforated bottom 6 for the purpose of keeping the air-openings clean. In order to enable the brushing device to adjust automatically, it is longitudinally movable on the axle 11. The air under pressure produced by the blower B entering through the tube 12, Fig. 1, and the cover 13 of the carbureter in the upper part of the air-tube 4 is therefore dispersed and serves to actuate the cleaning device 11 of the air-openings, effecting simultaneously a regulating of the shocks. Before entering the carbureter the air is led into an accumulator D, serving as an air-chamber. This air-accumulator consists of a closed vessel 14, the cover of which is provided with an outlet-valve 15 and provided internally with a pressure reducing device, Figs. 4 and 5. The latter consists, essentially, of a vessel 18, closed by a diaphragm 17 of flexible metal or india-rubber, and is divided by a horizontal partition 16 into two compartments. The diaphragm is rigidly connected to a vertically-movable rod 19, on which is secured a valve 20, closing a valve-seat in the partition 16. This valve is opened by the weight 21 of the diaphragm 17, so that the air entering below the partition passes through the valve 20 below the diaphragm. When the pressure of the air sinks below a certain point, the diaphragm collapses slightly inward, opening the valve 20 between thetwo partitions andso permitting air 0 to flow into the reservoir. From the upper chamber of the pressure-reducing device the air passes through an opening 21 in the accumulator l4: and fills the latter. The valve 15 is weighted by a weight-operated lever 22 9 3 and automatically opened by a suitable surcharge in the accumulator 14. Thus no more air enters in the carbureter as gas is consumed, while the superfluous uncarbureted air escapes through the outlet-valve 15.

In the accumulator is always a slight surcharge. When the outlets are kept opened, the air will 'pass through the carbureting liquid and escape carbureted. When all the outlets are closed, the air cannot pass into the carbureter, but will open the outlet- Valve 15 and escape through the same. Therefore no production of gas takes place. It is advantageous to lead the air through a second pressure-reducing device before it enters the carbureter, so that every shock is prevented. In the construction shown in the drawings there is shown a hot-air motor for the purpose of using part of the gas produced by the apparatus to actuate the motor, and while the air-current may serve for the cooling of the motor and also heating and drying of the air before it enters the carburetor, a part of the air heated by the motor may be led under the carbureter for the purpose of avoiding the formation of ice in consequence of cooling. The motor is of any well-known construction. On the lower cover the airheating tube 24: and below the latter the burner 25 are-arranged. The latter receives the gas through the gas-conduit, 27. The motor-cylinder is provided with ajacket 28. The air-current produced by the blower B is led through the tube 81 in the chamber between the jacket and the cylinder for the purpose of heating and drying the air. From this chamber the hot air passes through the tube 32 in the accumulator. From the heatingtube 24 a conduit 28 leads a part of the hot air below the carbureter for the purpose mentioned before. The blower B is actuated in well'known manner by means of the driving-rod 29 and the rocking axle 30, which is actuated by the fly-wheel of the motor. This apparatus is absolutely free from danger, and no surveying is necessary except the pressure to form the flame of the burner. The produced gas is suitable for direct and incandescent illumination, heating, and also for Working in explosion-motors. plosion-motor Working with the carbureted air produced by the generator may be used instead of the hot-air motor, the other arrangement not being altered. The flame 25 can serve to light the gas in the motor-cylinder The apparatus or to heat the glowing tube. can also be actuated by hand.
